And Boaz had gone up [to] the [city] gate and sat there. And look, the redeemer of whom Boaz had spoken [was] passing by. And he said, "Come over here to sit, {friend}." And he came over and sat.

And the redeemer said, "I am not able to redeem for myself, lest I ruin my inheritance. You redeem for yourself my kinsman-redemption, for I am not able to redeem [it]."

So the redeemer said to Boaz, "Acquire [it] for yourself," and he removed his sandal.

And the women said to Naomi, "Blessed be Yahweh who today {did not leave you without a redeemer}! And may his name be renowned in Israel!
